Oh, boy, you know how to stir up trouble, don't you! :-)

AnyLan was developed by both HP and AT&T, AT&T did the ASIC.  The truth
is that AnyLan was technically superior to 100BaseT, but it required
all 4 pairs to accomplish this.  That is really what killed it - there
were too many places that pair-split back then.

Another big problem with it was that the NIC's that HP made that were
AnyLan have a serious hardware bug - they would make the machine
crash if they were configured into PIO mode.  You had to configure them into
shared memory mode.

But, AnyLan lasted quite a bit longer than 5 months.  HP was making hubs for
it
for several years, and a number of big organizations got into it.
